Speciation in enterobacteria involved horizontal gene transfer. Therefore, analysis of genes
acquired by horizontal transfer that are present in one species but not its close relatives is …

Lipopolysaccharide (LPS) genes have many of the characteristics of PAIs but also differ in
significant ways. Lipopolysaccharide differs from the products of most PAI genes in that it is …

From a collection of 2,800 Tn 5-TC1 transposon mutants of Salmonella typhimurium F98, 18
that showed reduced intestinal colonization of 3-week-old chicks were identified. The sites of …

In order to identify genes belonging to the Fur regulon of Salmonella typhi which are absent
from Escherichia coli K-12, a plasmid gene bank consisting of 4000 independent clones was …

Summary In Salmonella enterica, the PhoP–PhoQ two‐component system governs
resistance to structurally different antimicrobial peptides including the alpha‐helical …

Using a genomic approach, we have identified a new Salmonella pathogenicity island, SPI-
4, which is the fourth Salmonella pathogenicity island to be identified. SPI-4 was located at …

Nitric oxide (NO) is associated with broad-spectrum antimicrobial activity of particular
importance in infections caused by intracellular pathogens. An insertion mutation in the metL …

Many mutations in rpsL cause resistance to, or dependence on, streptomycin and are
restrictive (hyperaccurate) in translation. Dependence on streptomycin and hyperaccuracy …

The sequence of the nonredundant region of the Salmonella enterica serovar Typhimurium
temperate, serotype-converting bacteriophage P22 has been completed. The genome is …

The ability of Salmonella enterica serovar Typhimurium to traverse the intestinal mucosa of a
host is an important step in its ability to initiate gastrointestinal disease. The majority of the …
